Phage j2, a lysogenic phage in Salmonella typhi J2, was shown to produce tiny plaques on various Vi type strains of S. typhi, to be a generalized transducing phage, and to have many characteristics including a serological one in common with phage P1 of Escherichia coli. Lysogenization of various S. typhi type strains with j2 or P1-group phages usually resulted in the alteration of the phage types of the S. typhi strains, except that phage j2 did not cause alteration of type 53. Phage j2 transduced, at high frequencies, much larger DNA molecules (up to at least 70 megadaltons) than those known to be transduced by Salmonella phage P22: this should prove useful for the genetic analysis of S. typhi.
噬菌体j2是伤寒沙门氏菌J2中的一种溶原性噬菌体，已证明它能在多种Vi型伤寒沙门氏菌菌株上产生微小噬菌斑，是一种广义转导噬菌体，并且具有许多特性，包括在血清学方面与大肠杆菌噬菌体P1有共同之处。用j2或P1组噬菌体对各种伤寒沙门氏菌菌株进行溶原化处理，通常会导致伤寒沙门氏菌菌株的噬菌体类型发生改变，但噬菌体j2不会导致53型发生改变。噬菌体j2能高频转导比已知沙门氏菌噬菌体P22转导的DNA分子大得多的DNA分子（至少达70兆道尔顿）：这对伤寒沙门氏菌的遗传分析应会有帮助。
